Hello! I am writing an application that requires access to the state

program using C++ accesses the information through SHM and I was
hoping to do the same with Python. I looked in PyPi and I noticed that
there was a module for SHM but I can not figure out where to download
it from (http://pypi.python.org/pypi/shm). Does anyone have any
suggestions?
Hi Sam,
I'm not familiar with that shm, however there was (and still is) a old
Python IPC module called shm. It uses Sys V semaphores, not POSIX
semaphores like the shm in pypi.
The old shm module has been replaced by two newer ones. For Sys V IPC:
http://semanchuk.com/philip/sysv_ipc/
For POSIX IPC:
http://semanchuk.com/philip/posix_ipc/
The old shm module is still around on semanchuk.com but I'm not
updating it anymore (the author is AWOL and I'm just the maintainer)
and I don't recommend using it.
HTH
